If I have the sender's private key, then I can pretend to be him. That
would mean that when you received an email from the sender, you couldn't
be sure if it actually came from him or not, thus defeating the purpose of
having a private key.

associates, telling them that my email address had changed to
industrial_espionage at spyware.com, please send all your confidential
information directly there thank you very much.
